These specialized needles are designed with a rounded tip, resembling a ballpoint pen. This unique construction allows the needle to slip between the fibers of knit fabrics, rather than piercing them. This prevents damage to the delicate loops and maintains the fabric’s elasticity and overall integrity. Common fabrics suitable for use with this type of needle include jersey, interlock, rib knit, and double knit materials.
Preventing snags, runs, and skipped stitches in knit fabrics is the primary advantage of using this needle type. The rounded point’s gentle interaction with the yarn structure preserves the fabric’s appearance and longevity. Historically, the development of this specialized needle arose alongside the increasing popularity of knit fabrics in garment construction. This innovation allowed for the efficient and damage-free sewing of these elastic materials, revolutionizing the apparel industry.
